Divide your life into at least three epochs. An epoch is a period of time in your life where a lot happened. On one hand, you can make "Elementary School" or "Middle School" an epoch. On the other, "That one week at summer camp" can be an epoch, if a lot of noteworthy events happened. 

Divide each epoch into at least three chapters. A chapter is an event from your life that helped to shape you. This can be an event that shaped you positively, or it can be something that you look back on with sadness or regret. Both types of memories are worth writing about. 

For each chapter, write at least 200 words telling the event like a story, and reflecting on the event. When reflecting, ask yourself how the event made you feel, what it made you realize about yourself, what it made you realize about others, how it made you who you are, etc. 

You must submit three chapters in order to get a badge. This can be one entire epoch, or it can be three chapters from different epochs. That part is up to you.
